Doger or Dogers are match-fixers. Of course they do not, have not and will not have any matches.
As a rule, fraudsters find gullible citizens who are interested in making easy money.
If a “dogger” finds 10 people, he will give 5 of them one outcome and give the other 5 the opposite. In the end 5 people will stay with him, after which the scheme will repeat itself. Be vigilant! Do not buy into scams!
